Cholesteryl Ester Storage Disease: Fatal Outcome without Causal Therapy in a Female Patient with the Preventable Sequelae of Progressive Liver Disease after Many Years of Mild Symptoms.

BACKGROUND Cholesteryl ester storage disease (CESD), also known as lysosomal acid lipase deficiency (LAL-D), is a rare autosomal-recessive inheritable lysosomal storage disease. Since 2015, a causal treatment with sebelipase alfa, which replaces the missing LAL enzyme, has been approved. We report a fatal course of LAL-D in a female patient. CASE REPORT In 1979, CESD was first diagnosed in a 13-year-old female with marked hepatomegaly. At that time, no specific treatment for CESD was available and the spontaneous course of the disease had to be awaited. In 2013, a laparoscopic cholecystectomy for symptomatic gallstones was performed. The patient's CESD had caused a Child-Pugh A/B and Lab-MELD 14 cirrhosis with esophageal varices (grade III), a solitary fundal varix, as well as hepatosplenomegaly with thrombocytopenia. In 2016, the patient was admitted with compensated cirrhosis and splenomegaly for a ligature of esophageal varices which was complicated by vomiting of blood followed by severe coagulopathy and hemorrhagic shock. The dried blood test showed reduced acid lipase (0.03 nmol/spot*3 hours; reference range 0.2-2) and beta-galactosidase (0.08 nmol/spot*21 hours; reference range 0.5-3.2). Then 15 days after the esophageal varices bleed, the patient died due to multiorgan failure as a sequelae of advanced liver disease. CONCLUSIONS LAL-D should be included in the differential diagnosis of lipid metabolism disorder, hepatomegaly, and non-alcoholic fatty liver disease with fibrosis or cirrhosis. Causal treatment with sebelipase alfa should be introduced even in patients who have LAL-D and many years of clinically mild symptoms of this disease to prevent the serious sequelae of cirrhosis or cardiovascular complications.

Hepatocellular carcinoma in Gaucher disease: an international case series.

Gaucher disease (GD) is associated with an increased risk for malignancies. Next to hematological malignancies, the development of solid tumors in several organs has been described. The liver is one of the major storage sites involved in GD pathogenesis, and is also affected by liver-specific complications. In this case series, we describe 16 GD type 1 (GD1) patients from eight different referral centers around the world who developed hepatocellular carcinoma (HCC). Potential factors contributing to the increased HCC risk in GD patients are studied. Eleven patients had undergone a splenectomy in the past. Liver cirrhosis, one of the main risk factors for the development of HCC, was present in nine out of 14 patients for whom data was available. Three out of seven examined patients showed a transferrin saturation > 45%. In these three patients the presence of iron overload after histopathological examination of the liver was shown. Chronic hepatitis C infection was present in three of 14 examined cases. We summarized all findings and made a comparison to the literature. We recommend that GD patients, especially those with prior splenectomy or iron overload, be evaluated for signs of liver fibrosis and if found to be monitored for HCC development.

Perioperative Therapy of Oesophagogastric Adenocarcinoma: Mainstay and Future Directions.

Perioperative chemotherapy improves overall survival in patients with oesophagogastric adenocarcinoma (OAC) and locoregional disease. The mainstay of perioperative chemotherapy in these patients is a platinum/fluoropyrimidine combination. The phase III FLOT4 trial has shown that the FLOT triplet regimen (oxaliplatin, infusional 5-FU, and docetaxel) improves the outcome of patients with OAC and locoregional disease as compared to the ECF triplet (epirubicin, cisplatin, and infusional 5-FU). Targeted therapies have currently no role in the perioperative setting for the treatment of patients with OAC. For patients with oligometastatic disease, upfront gastrectomy followed by chemotherapy did not show any survival benefit compared with chemotherapy alone and thus should be discouraged. Whether surgery should be offered to patients with metastatic OAC achieving a systemic control after upfront chemotherapy is under scrutiny in the phase III FLOT5/Renaissance trial. After neoadjuvant treatment, lymph node status but not pathologic tumor response is an independent factor in the prediction of overall survival. Growing evidence suggests that perioperative chemotherapy may be associated with an increased mortality risk in patients with microsatellite instable (MSI)/mismatch repair-deficient (MMRD) adenocarcinoma, thus validating poor responsiveness to chemotherapy in MSI patients with locoregional disease.
